It is time to act

When he was in the process of helping Rias, he could feel a great increase in mana in him, it was amazing and somehow the system started talking in his head.

System: [The user has received the 'Power of Destruction'].

He did not understand how he could get that technique from the Bael family, but when he wanted to ask, his body began to feel hot and he felt a change in his soul.

It was only for a few seconds but he felt, that if he repeated the fight against Gilbert, he could kill him in the blink of an eye.

But he noticed a lack of control in Rias' energy, it was too much mana for her to control.

-System, any solution to this problem?- he asked the question quickly, he could feel that the body of Rias would not resist much longer.

System: "The user can transfer a reinforcement technique."

He thought about it for a while, then decided to do it. He did not want Rias to explode suddenly as he had gotten a little affection for her.

-Well, purchase it and transfer it at the same time.-

* DING *

System: [The user has purchased 'Dark Tiger Technique'.]

System: [The user has transferred 'Dark Tiger Technique' to the host -Rias Gremory-.]

As soon as the notifications were over, he could feel a new strength in Rias, it was powerful and could be said three times the original.

---

When it was over, he opened his eyes and could hear Rias' little outburst.

Rias: "I ... I did it!" She got up jumping and smiling, it was quite strange because the series did not show this childish side of her.

He wanted to annoy her a little, but his gaze fell on a woman with nine tails, who looked at him kindly.

Yukio: "Yo! Yasaka, how are you?" He waved his hand in greeting mode.

Yasaka: "Well, we have not had any problems and in this place, there is so much mana that our wounded people have healed very quickly."

Yukio: "I'm glad to hear that." He was honest since the Yokai arrived here, they were quite nice and friendly.

Grayfia took a step forward and asked quickly.

Grayfia: "What is Yasaka the leader of the Yokai doing in this place?"

He found it funny, instead of asking what was the sudden transformation, she asked what Yasaka was doing here.

Yukio: "Yasaka-chan lives in this dimension with her faction, if you want to ask if I joined them, it's a no, I only gave them temporary housing."

Grayfia looked at Yasaka doubtfully.

As for Yasaka, she had a bit of a blush on her face, he called her Yasaka-chan in front of so many people, and she saw it, when she called him by the name of Yukio, that twenty-year-old boy appeared again.

Yasaka: "* Cough *" she coughed to hide her blush. "Is it true that you´re training the young heiress of Gremory?" She raised an eyebrow, it looked cute.

Yukio: "Yes, although it's kinda given and take as it stands, maybe you should help Kunou, don´t you think?" He smiled at her, he really wanted Kunou to become strong.

She just nodded and stayed by his side looking at Grayfia.

Rias: "Sensei?" Rias broke the awkward silence when approaching.

Yukio: "What's wrong?" He could see her acting strangely, he understood what it was, so he made her follow him.

Soon they moved away from the place, but for some strange reason, he felt an increase of energy coming from Yasaka and Grayfia. He´d look into it later.

Rias: "What is this technique called?" Inside her mind, there was the ´Dark tiger technique´, but she could not know exactly what it was useful for.

Yukio: "It's a technique that my teacher taught me. When you activate it, you will have some dark stripes on your body that increase your strength and agility, you can also expel or inhale the mana in your body. It's an ideal technique to unite your mana control, but keep in mind that the more you use it, the stronger you become, so you should start measuring how much you can take."

He explained patiently, they spent a few minutes talking and he could feel the energy of Yasaka and Grayfia exploding, he frowned at this, he did not know what they were doing.

Yukio: "I think it's time to leave."

Rias: "Uh ... Will Sensei come back to train me?" The girl asked suddenly.

Yukio: "Back to train you? With this technique along with mana control, I don´t think it's necessary."

Rias: "... How about you train me physically? You know ... you told me you can not always count on magic." She had a sad face.

He realized that it happened and smiled, he did not think this would happen.

Yukio: "Well, I give up, just tell Grayfia to bring you sometimes, but you must tell me before you want to come." He spoke as if he had not noticed her actions.

Rias seemed happy and animated, she approached and hugged him.

Rias: "Ejejej, in that case, I'll come several times." It seemed good to see her like that.

Yukio: "Let's go back to the others." She nodded and they went back to Grayfia and Yasaka.

Unknown to him, there was a pair of feline eyes that observed everything and soon he would receive many scoldings for "being unfaithful".

When he got to where they had left the two women, he could see destruction everywhere, in some places there were craters and some were burning.

He did not want to ask exactly why they fought, so he turned a blind eye to it, to get out of here.

Then a white portal appeared that swallowed them all, he saw that they created a circle to go to the Underworld.

For his part, he teleported with [Space Movement] to the house outside the city, he sat in a lotus position.

In front of him was a portal that he opened with [Space movement], his hand was inside trying to look for the mana of Akeno.

He just had to find someone who had the energy of a fallen angel along with human energy.

The reason for this ... He had to advance his plans! Reason? This...

System: [Fairies are in danger, a mission has been given to the host.]

System: [Save the Fairies, a new successor of 'Dragon of the abyss' your duty is to protect your home.]
